What the extension processes

Casper runs inside your browser. To generate a reply it sends the relevant chat messages, your persona and its own rules to our server, which forwards them to xAI (Grok) and returns the answer. Snaps and images a fan sends may be included for image understanding.

We don't store message content. Our server keeps only what's needed for billing: your license, balance, number of tokens per request, costs and dates. xAI processes requests under its own terms and privacy policy.

Chat memory (up to 60 messages per chat), fan notes, statistics and settings are stored locally in your browser's extension storage.

If you enable Telegram, notifications — including fan names and short conversation excerpts for HOLD and conversion alerts — are sent through Telegram to your own private chat with your own bot.

What we collect

Your email address — to deliver your license key, receipts and low-balance or service notices.
Payment records — order ID, amount, method, coin and network, and transaction hash, to match payments to licenses.
Usage records — daily totals of requests, tokens and credit used per license.
Support messages you send us.

Payments are processed by NOWPayments and, for cards, its on-ramp partners, which may verify your identity under their own privacy policies. Blockchain transactions are public by nature.
